Film forming aid CM-2
Environmental protection and clean taste film-forming aid CM-2
Overview
CM-II is an ester high-boiling organic compound, a colorless and transparent liquid, insoluble in water, soluble in latex particles. It is miscible with organic solvents such as ethyl alcohol, ethyl ether, acetone, benzene, toluene, ethane and esters. Mainly used as a film-forming aid for emulsion polymers. After adding this product, it can effectively reduce the film-forming temperature, improve the scrub resistance of the paint film, improve the uniformity of the pigment, have good color development, improve the adhesion of the paint film, and reduce the cracking and peeling of the paint film. Under the harsh conditions of low temperature and high humidity, it still has good film-forming performance. It is widely used in pure acrylic, styrene acrylic, vinegar acrylic, silicon acrylic and other emulsions; it can also be used as a solvent for acrylic baking paint and other baking paints, and as a high boiling point solvent in printing inks, textile dyes and advanced baking enamels.

Use and usage
CM-II is a film-forming aid with excellent performance for latex paint, which can greatly improve the film-forming performance of latex paint. It is not only effective for pure acrylic, styrene-acrylic, and vinegar-acrylic emulsions, but also for vinyl acetate The lotion is also effective. In addition to significantly lowering the minimum film-forming temperature of latex paint, it can also improve the film properties of latex paint such as weather resistance, scrub resistance and color development.
The addition amount in latex paint mainly depends on the Tg value of the emulsion polymer. High Tg value emulsions need to add more addition amount to achieve the desired film-forming effect. The addition amount in latex paint (based on the solid content of the emulsion) is 3% to 6%, which can be adjusted at any time according to the different types of emulsions and construction methods, and the general addition amount is 2% to 4%. The method of adding CM-11 in the production of latex paint is very simple. In principle, it can be added at any stage of the production, but for some systems, in order to avoid the gel phenomenon and better miscibility during the addition process, you can first add CM-II should be mixed with a certain amount of water and surfactant in the production of latex paint, and then the mixed solution can be added to the emulsion. If it can be added in two times, its effect can be fully exerted. Add 1/2 amount during the grinding process to help wetting and dispersing the filler. Add 1/2 amount in the paint let-down stage to help suppress the generation of foam.
